600um large core energy transmission optical fiber

We are currently able to provide international commercial-level quartz energy optical fibers in batches. Our energy optical fibers include two categories: quartz cladding type high-performance energy optical fibers and plastic cladding type high-performance energy optical fibers. Quartz cladding type energy optical fibers can transmit higher laser power, have good resistance to optical damage, as well as lower attenuation and higher light transmittance (from near ultraviolet band to near infrared band 400nm ~ 1600nm).

5W 1550nm Single-mode Single Stage Fiber Isolator 28dB

Idealphotonics’ fiber isolator products can maintain excellent return optical isolation performance under any polarization state. It has low loss, high isolation, high return loss, low polarization-dependent loss, low polarization mode dispersion, wide operating band and operating temperature range, and no glue in the optical path. These properties provide the possibility for low-cost solutions for communication networks. This series of products can be used in erbium-doped amplifiers, wavelength division multiplexing systems, fiber optic equipment and lasers.

1550nm Single-Mode Fiber Reflector

Examples of fiber total reflection mirrors used in erbium-doped fiber amplifiers. In this application, a fiber-based back reflector is placed at the end of an erbium-doped fiber, reflecting light back into the fiber in the direction of the incident light. A circulator is used to direct both the input and amplified output signals along their respective optical paths. This setup allows the signal light to pass through the gain fiber twice, effectively enhancing the amplifier's gain absorption efficiency. Another practical application of back reflectors is the construction of tunable back reflectors, as shown in Figure Feedback signals from a downstream back reflector can cause instability in certain devices, such as laser diodes. By incorporating a tunable back reflector, the sensitivity of a device to back reflection can be determined. A tunable attenuator enables users to introduce a controlled reflection into the system. By analyzing the effects of back reflection, users can calculate parameters such as noise level, bit error rate, and distortion.

1310nm 3X3 Single Mode Fiber Coupler

The NIR-FBC-W1216 NIR series single-mode fiber coupler is developed based on our single-mode fiber fusion tapering machine IPCS-5000-SMT. It is a high-performance coupler designed for splitting light in the near-infrared wavelength range, covering the entire communication band (1260-1620nm). We also offer high-cost-performance narrowband couplers with center wavelengths of 1310nm, 1392nm, 1480nm, 1512nm, 1550nm, 1650nm, and 1742nm, with a bandwidth of ±20nm. Our couplers, available with connectors or bare fiber, can handle a maximum power of 1W, and are manufactured using a one-time fusion tapering process. These couplers are reliable, compact in size, and ideal for fiber optic sensor applications

1310nm 1X4 Polarization Maintaining Fiber Coupler Module

Idealphotonics’ low-profile couplers have inherent performance advantages because the waveguide core is not deformed or tapered. These devices have low losses and back reflections. Also, the short interaction length (1-2 mm) allows for small device packaging. The interface is essentially vanishing in optical contact between identical silica surfaces. There is no intermediate material that changes its refractive index or thickness with age or environmental influences. The optical performance of the couplers is as if the fibers were molten and is very stable under temperature variations. The fibers are side-polished in a glass substrate block to remove the cladding material on one side of the core without distorting the core region. For PM fibers, only one stress member remains. The two polished fibers are brought into optical contact with their polarization axes aligned and coupling between the cores is achieved by the evanescent wave interaction. Precise loading of the substrate block ensures that the fibers remain in low-stress contact over a wide temperature range.

ZBLAN Mid-Infrared Large Core Power Transmission Fiber, Core Diameter 160μm

ZBLAN fiber is a composite glass fiber composed of heavy metal fluorides such as ZrF4, BaF2, LaF3, AlF3, and NaF. Compared to the widely used silica fiber, ZBLAN fiber offers a wide transmission wavelength range (0.35μm to 4μm) and high emission efficiency when doped with rare earth ions. Through the development of a unique fiber manufacturing technology, Idealphotonics Optics has introduced a low-cost method to produce high-quality (especially low-loss) fluoride fibers.

405nm single mode fiber optic connector/patch cord

Fiber optic patch cords (also known as fiber optic connectors) are optical cables with connector plugs installed on both ends to achieve active connection of the optical path. Xiaoxiao Photonics' fiber optic patch cords have high-quality, narrow-pin ceramic FC/AFC connectors on both ends. Produced by our equipment, each patch cord is individually tested at the test wavelength listed in the specification label to ensure the extinction ratio and low back reflection (return loss) when connecting fibers. These patch cords are in stock and have high-quality polishing to ensure a typical return loss of more than 60 dB.

405 nm Polarization Maintaining Fiber Optic Connector/Patch Cord

These polarization-maintaining fiber optic patch cords feature high-quality, narrow-key ceramic FC/AFC connectors on both ends. Produced by our equipment, each patch cord is individually tested at the test wavelength specified in the specification label, ensuring extinction ratio and low back reflection (return loss) for both the fiber and its connections. These patch cords are in stock, featuring high-quality polishing to guarantee a typical return loss exceeding 60 dB. The test data sheet provides the extinction ratio and insertion loss test results for each patch cord. Each patch cord comes with two protective caps covering the ends to prevent dust or other contaminants from settling on the ferrule end face. We also sell protective FC/PC end caps separately, including CAPF plastic fiber caps and CAPFM metal threaded fiber caps. If you cannot find a suitable product among our in-stock patch cords, Terahertzlabs also offers custom patch cords that can be shipped on the same day.
